Versuchsvorschrift

To a solution of 1-(4′-chlorobiphenyl-3-yl)-N-(4-fluorobenzyl)methanamine (70 mg, 0.22 mmol) in THF (4 mL) were added 3,5-dichloro-2-hydroxybenzenesulfonyl chloride (61.8 mg, 0.24 mmol) and TEA (0.08 mL, 0.54 mmol). The resulting mixture was stirred at rt for 1 h and concentrated in vacuo. The residue was dissolved in MeOH and purified by preparative HPLC. Fractions containing the desired product were combined, concentrated, and lyophilized to give the title compound (46 mg, 39%) as a glassy solid. 1H NMR (CD3OD) 7.59 (d, J=4.0 Hz, 1H), 7.43 (d, J=4.0 Hz, 1H), 7.36-7.35 (m, 5H), 7.22 (t, J=8.0 Hz, 1H), 7.16-7.09 (m, 5H), 7.05-7.03 (t, J=8.0 Hz, 1H), 6.90-6.85 (m, 2H), 4.46 (s, 2H), 4.41 (s, 2H). MS (ESI): 550.0 (M−H)−.
